When Stephen was 21 he was informed he had motor neuron disease and that he likely only had two years to live. He is now 72 and one of the greatest physicists alive (if not the). In addition he is a professor at the University of Cambridge, best known for his discovery that black holes emit radiation which can be detected by special instrumentation. His discovery has made the detailed study of black holes possible.

So much like Einstein, when Stephen speaks it’s probably worth your time.

On disability

“My advice to other disabled people would be, concentrate on things your disability doesn’t prevent you doing well, and don’t regret the things it interferes with. Don’t be disabled in spirit, as well as physically.”

3

On priorities

“My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.”

4

On free will

“I have noticed that even people who claim everything is predetermined and that we can do nothing to change it, look before they cross the road.”

5

On humor

“Life would be tragic if it weren’t funny.”

6

On his IQ

“I have no idea. People who boast about their I.Q. are losers.”

7

On what he thinks about all day

“Women. They are a complete mystery.”

His advice to his three children

“One, remember to look up at the stars and not down at your feet. Two, never give up work. Work gives you meaning and purpose, and life is empty without it. Three, if you are lucky enough to find love, remember it is there and don’t throw it away.”

On why he writes for a popular audience
“I put a lot of effort into writing ‘A Briefer History’ at a time when I was critically ill with pneumonia because I think that it’s important for scientists to explain their work, particularly in cosmology. This now answers many questions once asked of religion.”

10

On hitting roadblocks

“It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years.”

11

On the value of string theory

“When we understand string theory, we will know how the universe began. It won’t have much effect on how we live, but it is important to understand where we come from and what we can expect to find as we explore.”

12

On God

“God may exist, but science can explain the universe without a need for a creator.”

13

On his health

“When I was first diagnosed with ALS, I was given two years to live. Now 45 years later, I am doing pretty well.”
